Objective To sum up the experience of renal transplantation in order to improve transplant effect and enhance the long-term survival and recovery rate.Methods The data of renal transplantation of 1 124 cases who received renal transplantation from Jul. 1978 to Oct. 2001 were summarized. All the possible factors that could influence the transplant effect such as pre-operative preparation, HLA match, donors' quality, surgical procedure, immunosuppressive therapy and so on were analyzed. Results The 1-, 3-, 5-year survival rate (%) of patient/kidney was 83.1/ 70.3, 74.6/ 68.6 and 62.6/ 56.1 respectively. The rate of AR was decreased significantly from 3.09?% only with LXM to 0.89?% with LXM test in combination with HLA serological test. The rate of HAR and AR in 130 cases with additional PRA test were lower than those only with LXM test.Conclusions The well pre-operative preparation, the ideal HLA match, the high quality of donor's kidney and transplant operation were keys for successful renal transplantation. Reduction of the complications, individual and combined medication in reason and long-term follow-up were very important in the long-term survival time.

Objective: To explore the relationship between social support and internet addiction in undergraduates. Method: 382 undergraduates were divided into three groups according to their social support score and perceived social support score at end of the first term in their freshmen year. They were followed for 4.5 years to collect the incidence of internet addiction. Results: The group with less social support or less perceived social support had higher incidence rate (15.7%, 7.9% and 2.4% with social support score 0～60, 61～73 and higher than 73 respectively, ?2=9.49,P=0.009). There was obvious dose-effect relationship between social support and incidence of internet addiction. Conclusion: Less social support is a risk factor of internet addiction.

BACKGROUND:Reversible posterior leukoencephalopathy syndrome is rarely reported, especial y concurrent during perioperative period of renal transplantation. Due to its clinical manifestations similar to uremia, transplant doctors are easy to ignore or not timely diagnosis reversible posterior leukoencephalopathy syndrome, thus impacting its treatment.
OBJECTIVE:To discuss the clinical manifestations, imaging features, treatment experience and prognosis of patients with reversible posterior leukoencephalopathy syndrome concurrent during perioperative period of renal transplantation, in order to improve the diagnostic rate and therapeutic effect.
METHODS:We reviewed clinical data of one case of concurrent reversible posterior leukoencephalopathy syndrome during perioperative period of renal transplantation admitted at the General Hospital of Shenyang Military Region.
RESULTS AND CONCLUSION:From the 3rd day postoperatively, the patient gradual y experienced abnormal blood pressure, blurred vision, headache, seizures, disturbance of consciousness and mental and behavioral abnormalities. Early head CT showed low density in the left frontal lobe and corona radiate;and further MRI re-examination showed flake-shaped T1 and long T2 signals in the bilateral frontal lobe, hippocampus, parietal occipital cortex, and brainstem, as wel as high signals on FLARI images at the corresponding parts. After active treatment, the clinical manifestations were improved. Retrospective analysis of clinical data of this case and review of relevant literature wil provide clinical data for the diagnosis and treatment of concurrent reversible posterior leukoencephalopathy syndrome during perioperative period of renal transplantation.

BACKGROUND: Anemia after kidney transplantation has a clinical incidence rate of 30%-40%, is the important risk factor for cardiovascular diseases and kidney failure after kidney transplantation and is also the independent prediction index of patient's death. OBJECTIVE: To analyze the factors related to anemia after kidney transplantation. RESULTS AND CONCLUSION: In the anemia group (n = 225, 27.2%, aged 26-65 years), the incidence rate of anemia in female and male patients was 23% and 37%, respectively (P < 0.05), 46 patients had hypertension and used angiotensin-converting enzyme inhibitor or angiotensin Ⅱ receptor antagonist and 16 patients had chronic erosive gastritis or upper gastrointestinal tract ulcer, with the human survival rate of 85.3% and kidney failure rate of 25.3%. In the non-anemia group (n = 601, 72.8%, 405 males, 196 females, aged 18-71 years), 35 patients had hypertension and used angiotensin-converting enzyme inhibitor or angiotensin Ⅱ receptor antagonist and 14 patients had chronic erosive gastritis or upper gastrointestinal tract ulcer, with the human survival rate of 92.1% and kidney failure rate of 12.6%. There was significant difference in above-mentioned indices between anemia and non-anemia groups (P < 0.05). These results suggest that gender, age, kidney function, digestive tract disease history, and drug application are closely related to anemia after kidney transplantation.
